"The Code of a Good Sport" 

1. Thou shalt not quit. 

2. Thou shalt not alibi. 

3. Thou shalt not gloat over win- 
ning. 

4. Thou shalt not be a rotten loser. 

5. Thou shalt not take unfair ad- j 
vantage. 

6. Thou shalt not ask odds thou 
art not willing to give. 

7. Thou shalt always be ready to 
give thine opponent the shade. 

8. Thou shalt not under estimate 
an opponent, nor over estimate 
thyself. 

9. Remember that the game is the 
thing, and that he who thinketh 
otherwise is a mucker and no 
true sportsman. 

10. Honor the game thou playest, 
for he who playeth the ^ame 
straight and hard wins when 
he loses. 

— H. S. Fuller ton in N. Y. Evening Mail.

AUTHOR'S NOTE 



For many years the writer has thought 
that a checker compilation on forced lines, 
would enable the beginner to get away to 
a better start. 

The average player will spend twenty 
years selecting certain lines, and meanwhile 
he has delved into so many variations which 
fill his mind to such an extent that he has 
no brain space left for strong lines of play. 

I believe the reader will agree with me 
when I state that there is a limit to the 
human brain, otherwise a world's champion 
would never lose a game. 

It took the writer twenty-five years to 
collect these ffames, which have been 
selected from all sources and I have given 
credit as near as possible. If the reader 
will concentrate on these lines and not allow 
himself to be sidetracked on other lines, he 
will soon be able to hold his own with very 
good players. 

Do not try to solve problems, but commit 
them to memory, at least one end-game 
problem daily. 

The play is arranged so that the student 
will have a nucleus to build on when ready 
to branch into two-move style of play. 

The method and matter of the book are 
both obvious and students will discover its 
scope and character by simply turning over 
the leaves, hence no detailed exhibit of the 
plan seems to be called for. 

I wish you good luck. 

ANKER JENSEN. 

P. S. — A good excuse is not as good as a 
draw. — A. J. 

August, 1921.

The Numbered Board 



The checker board is numbered corres- 
ponding to the diagram below.

For the first section of this book for the 
black side of all openings, the board is 
numbered bottom to top, as diagram. 

The black pieces always occupy the first 
twelve small numbers, thus: 1, 2, 3, 4, 5, 
6, 7, 8, 9, 10, 11, 12. 

The white pieces, therefore, will occupy 
the last twelve numbers, thus: 21, 22, 23, 
24, 2>5, 26 27, 2S, 29, 30, 31, 32. 

The first move is invariably made by 
the player having the black pieces. And 
the player shall play alternately with the 
blacks and v^^hites. Thus the numbering 
will change from one side to the other.

Black to play. 

The above position has puzzled the experts for a 
half century to find the best line for black to follow. 
If there is a choice it is 4-8, 29-25, 2-6 as below. 
Black has a strong game and at the same time 
avoids all complications.

Black to play 

Forms Single Corner, which is popular with ail 
classes of players. The Single Corner is the most 
interesting opening on the checker board and con- 
tains more play than any other ten openings com- 
bined. 

No man will live long enough to learn all of 
Single Comer as it is inexhaustible, and the endings 
that arise from this opening are numbered among 
many thousands of problems. Time spent on Single 
Comer is sure to prove profitable to the student. 

As the position stands above, black has a choice 
of 12-16, 8-11, 10-15, 10-14, 9-14 and 9-13. Tliey 
all lead to wonderful combinations and which is the 
stronger is a matter of opinion, as it depends a good 
deal on how much your opponent happens to know. 
You may trip him on one line and lose on another, 
and the reverse may happen with a different player.

WHILTER 

Black Side 



11-15 23-19 9-14 22-17 

And then the question arises, which is th| 
next best move for Black. The writer considers 
9-14 as the most confining, for White can only 
choose 27-23 for Defiance, or 22-17 which allows 
Black great scope. See diagram below. 




Black to play- 
Black has choice of several strong attacks 5-9 

Fife, 6-9 Souter, 8-11 leads to Alma, Old 14th and 

Glasgow. 

It requires years of study for the student to 

defend the White against any and all Black attacks. 
The Whilter was selected as it is very easy to 

draw with a small amount of play, which leaves 

more time to devote to other and harder openings.

larker, A. 


Jordan. 



A — In unrestricted play 22-18 is usually the best^ 
but the writer considers 24-19 easier, as it is more 
confining. 

In opening 9-13, 24-19 Black can only reply 11-15 
or 11-16- whereas in opening 9-13, 22-18 black can 
reply 6-9, 10-15, 11-15, 11-16, 12-16 or even 10-14, 
and although they are all weak, the variety is 
enough to cause White a whole lot of study. 

B — At this stage most players cut 18-14, but ex- 
amination of published play shows that White has 
more winning chances with 25-22 and the idea is to 
hold back the 18-14 cut as long as possible.

PRACTICAL ENDINGS 



This work is too limited to include enough prob- 
lems for the student and we suggest the reader 
procure Wood^s, Gould'^ and HorsfalVs problem 
bocks. 

Wood's contains ^verytMng needed in 2x2 study, 
and Gould^s contains a section on bridge positions 
which alone are worth the price of the book, and 
Ilors fall's is a wonderful <iollection.

a — The play to this 
point has little dispute 
— but from here on! 



This position was drawn as the 80th game in the 
Jordan-Banks match, but in their 1917 match 
Banks varied and scored a very clever win. Since 
then a great controversy has occurred, Mr. Titus 
contending that the position is only a draw after 
all. Thousands of variations have been worked 
out, and while most of them favor a white win, the 
question is still at issue and awaits definite 
determination.

Black j\imps first, then White; the pieces jump 
the same as Kings, forwards and backwards, and 
the trick is in the last jump. White lands on

GREENOCK'S OUTDOOR CHECKER BOARD 



No. 4 — Contributed by Hugh McKean 

Probably the largest checker board in the world is 
to be found in Wellington, Park, Greenock, Scotland. 
This board is eight feet square and is formed in the 
ground by means of slabs of iron, which form the 
black or playing squares of the board, the white 
squares being filled in with concrete. 

This large checker board has iron men which 
weigh fifteen pounds, measuring six inches in diam- 
eter, boss inside, with a large keyhole into which 
iron cleeks the length of walking canes are inserted, 
by which each player moves his men. 

The black men are round, the w^hite men square, 
and w^hen a piece is crowned the bottom piece is 
turned up with a rim embossed side to denotie a king. 

There is also a concrete walk around the board, 
with several benches set around for the benefit of 
spectators. 

The space occupied is about forty square feet, with 
beautiful shade trees on the spot, from which there 
is a splendid view of the Scottish Highlands and the 
famous river Clyde, which is seven miles wide at this 
point.

Checker Curios — Continued 



The three following curios were taken from Alfred 
Jordan's column in Los Angeles Express. 

The games are remarkable as they show how it 
is possible for the Black and White pieces to change 
places. 

In No. 7 the object is attained with the fewest 
possible number of kings. 

In No. 8 White is handicapped by being compelled 
to copy every move that Black makes. 

Of course no piece must ever be left where it *could 
be taken. Some of our readers may find it amusing 
to try to work out a similar game for themselves. 

Most of the play in No. 7 is by Dr. Brown, and 
No. 8 was shown to Mr. Jordan by A. Woolhouse. 

A good supply of extra pieces for crowns will be 
desirable.

No. 9 

Some poor players imagine that as they are gen- 
erally losing they would be wonders at the losing 
game. The general opinion of such players is that 
in a losing game it is an advantage to have only a 
few pieces to get rid of while the opponent has a lot. 

The following game will show the fallacy of this 
idea. The ending is very critical and is said to 
have cost $500. 

The loser contended that the ending was only a 
draw, but the winner demonstrated a little point that 
proved the win.

A — The only move. 

B — Again the only move, 16-12 loses by 7-10. 

C — The position was left at this point as a win for 
Vv^hite, but a critic wagered $500 to prove a 
draw\ 

D— All White can do, 18-14 or 18-15, loses by 22-26. 

E — Black now felt secure, as he could draw with ease 
if the two White men w^ere Kings. 

F — This is the point. If White crowned his man it 
would be a draw. 

G — The settler. Black cannot play 15-10, as he 
would like to do, because of 9-6, which would 
leave White without a move. He is therefore 
compelled to allow White to cross the line by 
9-6, after which there is ^'nothing to it".

Mr. Mercer devoted a great part of his spare time 

to drafting a set of (proposed) Standard Rules, to 
govern the playing of checkers by correspondence. 

The Rules cover Checker Tourneys, Team Matches 
and Individual Matches, and have been highly rec- 
ommended by Experts in correspondence play.

And now we have a position that proved too 
tricky for three famous players, in three different 
championships, and a curious coincidence about it 
was that all their names began with B. 

They all moved 15-18 which allows a draw by 
16-19, 32-27, 19-23, Drawn.

The next instance was N. Banks in his match with

In Position No. 6 white must prevent the black 
king from joining the man on 3 or a draw will 
result. 

With an extra piece on the board different 
methods are sometimes employed to win the game. 

The following positions each illustrate a point 
which the student will easily locate by trying to

DAMEH 

It is those who love her best 

Sweet Dameh doth her gifts outpour 

From out a won'drous treasure chest 
Filled to the brim with gems galore. 

What though outsiders mocking gaze? 

She pities them ! They ne'er have trod 
Enchanted squares in a mystic maze 

Upon her fair historic " brod,*' 

But let them once her pleasures know — 

And lo ! the won'drous deed is wrought. 

Their love for her shall ever grow 

And all their scoffing turn to naught. 

And as they journey on through life 

They'll sing her praise to many friends- 

The struggle rife with mimic strife — 

'Till death, itself, the 'chantment ends. 

— WILLARD E. DAVIS,

There are recorded more than seven thousand kinds 
of contests and games that involve the matching of 
brain, eye, or muscle. They range from pinochle to 
prize fighting. Checkers is only one of this number. 
More than two hundred champions are recorded in 
the books. We are always engaged in some kind of 
a struggle ; always "playing the game" somehow or 
other. It may be a competition against other human 
beings, or it may be a fight against circumstances. 
Probably there isn't a day when you do not have a 
chance to show whether you are "a good sport." — 
Fulierton. 






No matter how old or what your position in life, 
checkers will benefit you in a multitude of ways. 
Besides the memory drills, exercises which are an 
educational equal to any ; the pastime develops self- 
reliance, originality and concentration, which must 
increase your ability along business lines. Cali- 
sthenics of the mind develop as physical training de- 
veloi s the musc'es. You do not have to have a 
dynamic mind for the game or be bom with any 
special intuitive gift to enjoy the captivating or 
fascinating qualities. Baseball has its short season, 
but checkers, like Tennyson's brook, "goes on for- 
ever." — E. H. Bryant, in Portland Oregouian.
